Abstract

In this study, Ni-Co-W-B metallic glass alloys were developed as precursors to produce a composite material group with high hardness, high fracture toughness, high temperature oxidation resistance and high corrosion resistance. The alloy that forms the basis for the studies carried out for the development of Ni-Co-W-B metallic glass alloys with low boron content is Ni42.6Co20W20B17.4 alloy. In order to determine the alloys with the highest glass forming ability, the amounts of Ni, Co and W were systematically changed. As a result of these studies, metallic glass alloys containing 13 at.% B and 15 at. % B were developed. It was determined that the critical casting thicknesses of all alloys with 13 at.% B and 15 at.% B content were 0.3 mm.

Özet

Bu çalışmada yüksek sertliğe, yüksek kırılma tokluğuna, yüksek sıcaklık oksidasyon direncine ve yüksek korozyon dayanımına sahip bir kompozit malzeme grubu üretmek için kullanılacak öncül Ni-Co-W-B metalik cam alaşımları geliştirilmiştir. Düşük bor içeriğine sahip Ni-Co-W-B metalik cam alaşımlarının geliştirilmesi için yapılan çalışmalara temel oluşturan alaşım Ni42.6Co20W20B17.4 alaşımıdır. Camlaşma kabiliyeti en yüksek alaşımları belirlemek için Ni, Co ve W miktarları sistematik olarak değiştirilmiştir. Bu çalışmalar sonucunda %13 B ve %15 B içeren metalik cam alaşımları geliştirilmiştir. % 13 B ve % 15 B içerikli alaşımların hepsinin kritik döküm kalınlıklarının 0.3 mm olduğu belirlenmiştir.
